Lock catch component

Abstract

The invention relates to a lock catch component which is used for being arranged on a braid of a safety belt system, the lock catch component comprises a lock catch body and a sliding cover which can be arranged on the lock catch body in an up-down sliding mode, the sliding cover comprises a shoulder strap abutting beam located on one side of the lock catch body, and the braid bypasses the bottom end of the shoulder strap abutting beam and then penetrates through the sliding cover and the lock catch body, the sliding cover can be pushed upwards to the locking position by means of the action of the tension of the shoulder strap section of the braid on the shoulder strap abutting beam, so that the sliding cover and the lock catch body relatively clamp and lock the braid, and the function of locking the braid cannot be lost due to the fact that the tension of the waist section of the braid becomes small or disappears, and the problems that the waist belt section of the braid is transferred into the shoulder belt section through the lock catch component, so that the safety belt system loosens the restraint to the human body and the like can be solved.

Description

technical field [0001] The invention relates to a buckle member of a safety belt system, especially a buckle applied to a safety belt system of a seat of a transport vehicle and installed on the ribbon of the safety belt system so as to be able to connect with the side of the seat Interlocking locking components. Background technique [0002] At present, it is used in transportation vehicles such as motor vehicles. In order to ensure the safety of drivers and passengers, seat belt systems are installed on the seats of transportation vehicles. The safety belt system is to extend the webbing pulled out by the webbing retractor on one side of the seat upwards through the upper ring on the side wall of the vehicle body, and then extend downwards and install a locking member, which is attached to the other side of the seat. One side is provided with a buckle. When the user sits on the seat, the buckle member connected to the webbing is buckled with the buckle on the other side ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a locking member to solve the problem that the tension in the belt section changes instantaneously due to the force acting on the belt section of the ribbon changing with the shaking of the user's body in the existing webbing locking member. When it is small or disappears, it is easy to cause the sliding part to return to the unlocked position and lose the function of locking the webbing, and before the tension of the waist belt section is restored and the sliding part locks the webbing, a part of the waist belt section of the webbing will pass through the locking member. Transferred to the shoulder belt section, causing problems such as the seat belt system loosening the restraint of the user's body
